Rand Paul is best known for thirteen-hour filibusters, but he's also willing to use the occasional four-letter word.

The Kentucky senator and 2016 Republican presidential candidate was hitting back against national surveillance last week in a room packed with young supporters: "So when they stand up on television and say, the tragedy in Paris means you have to give up your liberty, we need more phone surveillance—bullshit!" ...

Paul isn't backing down. He's continuing to argue against trading liberty for security. He's disputing whether the surveillance powers demanded by the government to fight terrorism will even work. And he's pointing out that military adventures from Iraq to Libya have created the chaos that has allowed ISIS and other barbaric jihadist terror groups to thrive....

Why propose invading and occupying the foreign countries from which terrorists come rather than securing our own country's borders and interior? If the latter is impractical and "isolationist," how can the former ever work? France was plainly more vulnerable because it had a large population of unassimilated Muslims at home willing to work with those from abroad who would do the French harm.
